SHAKING MECHANISM FOR SEPARATORS.

Specification of Letters Patent.

Patented. Nov. 19, 1907.

Application filed August 15,1906. Serial No. 330,851.

To all whom it may concern:

Be it known that we, FRANK Onirnnii and THOMAS CHIPERA, citizens of theUnited States, residing at Breckenridge, in the county of WVilkin, Stateof Minnesota, have invented certain new and useful Improvements inShaking Mechanism for. Separators; and we do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to shakers for grain separators, threshingmachines and the like and has for its object to provide a constructionof this nature which will act efficiently to loosen bundles of straw.

A novel feature of this invention resides in the fact that an adjustablerake bed is provided, by means of which the throw of the rake bars abovethe rake bed may be regulated, if so desired.

Furthermore the invention resides in the provision of a rake bed formedin sections which may be tilted to locate the sides of the rake bedabove the level of the middle thereof to cause the straw to be fed tothe center of the bed, thereby thoroughly loosening up the bundles ofstraw.

A still further object of the invention is to so construct the supportsfor the bars of the rake bed that these Su ports will maintain avertical position andt fierefore not interfere with the rake bars.

With these and other objects in view, the invention consists in theconstruction and arrangement of parts shown in the accompanying drawingsin which Figure 1 is a top plan view of the invention. Fig. 2 is avertical, longitudinal, sec tional view through the mechanism. Fig. 3 isa bottom plan view of the same, the bottom of the casing being shownpartly broken away and Fig. 4 is a detailed, transverse, sectional viewthrough one side of the mechanism showing the means for adjusting therake bed.

Referring more specifically to the drawings, the numeral 5 denotes thesides of the casing in which the mechanism is arranged and 6 the bottomof the same. Journaled in the said sides of the casing intermediate ofthe ends thereof is a multiple'crank shaft 7 and in the said sidesadjacent each end of the casing, is journaled a multiple crank shaft 8.The numeral 9 denotes rake heads which are connected with and supportedby the cranked portions of the multiple crank shafts 7 and 8, the saidconnection being made by means of suitable bearing boxes 10. There are aseries or these rake heads for each series of cranked portions of theshafts 7 and 8 and the cranks of the said shafts extend in oppositedirections, so that the series of rake heads will be moved alternately,upwardly and downwardly.

Supported by each series of rake heads 9 is a series of'parallel rakebars 10 which are provided at intervals under their upper edges withrake teeth 11. Said bars are supported by means of brackets 12, whichcomprise each a strip of metal bent upon itself as at 13 to form spacedportions which lie upon opposite sides of the respective rake headswhich are secured thereto in any suitable manner, said spaced portionsbeing bent to extend in diverging planes as at 14 above the upper.

edges of the said head and secured to the under edges of the respectiverake bars 10 in any suitable manner.

In order that the shafts 7 and 8 may be driven to operate the rakemechanism as above described, a crank wheel 15 is mounted upon the shaft7 and is provided with a crank pin 16 for the attachment of theconnecting rod, therewith from any suitable source of power, whereby thesaid shaft may be rotated.

The crank wheel 15 above mentioned is located at one end of the Shaft 7and located at the opposite end of the said shaft and at thecorresponding ends of the shaft 8 are crank disks 17 carrying crank pins18 and connecting the crank pins of the crank disks 17 is a connectingbar 19, it being understood that when the shaft 7 is rotated, shafts 8will also be rotated and in the same direction.

Mounted at its ends in the sides 5 of the casing, adjacent each endthereof, and intermediate the shaft 7 and the adjacent shaft 8 is a beam20. A standardQl is supported by each of the beams intermediate the endsthereof and supported by the said standards at their upper ends is oneof a series of bars 22 whichconstitute the rake bed, the said bars beingin parallel relation with respect to the rake bars 10. Hingedlyconnected at their inner ends to the standards 21 upon opposite sidesthereof and extending in a vertical plane with respect to the beam 20are beams 23. Each of the beams 23 is recessed at intervals in its upperedge as at 24 and pivoted at their lower ends in each of the saidrecesses 24 is a standard 25. Supported by the corresponding standardsand rake Ears are the remaining bars 22 of the rake In order that thebeams 23 may be adjusted and cause them to assume an inclined positionwith their outer ends above the level of their inner hinged ends, eachof the said beams is provided in its under side and at its outer endwith an interiorly enlarged recess 26 in which isengaged a ball end 27of a threaded adjusting rod 28, said rod being engaged througha bore 29in the beam 20 and provided at its lower end with a crank handle 30 bymeans of which it may be rotated to raise and lower the said outer endof the beam 23.

As a means for holding standards in an upright or vertical position, abar 31 is pivotally engaged as at 32 with the standards supported byeach beam 23 and adjacent the lower end of the said standards and hasits outer end extending through a slot 33 formed adjacent the side .5 ofthe casing in which the mechanism is mounted. Secured upon the outersides of the casing upon each side of each slot 33 formed therein is aguide 34 including a right-angularly extending portion 35 which formstogether with the adjacent portion of the side of the casing, a guidechannel, 36. Each bar 31 is provided at its said outer end with a pin37, the ends projecting beyond the sides of the bar in the guide channel36, it being understood that by this means, when the beams 23 areadjusted the standards 25 will be simultaneously moved to assume avertical position with respect to the beam 20.

As shown in the drawings, the beam 20 has a fixed elevation, but when itis desired, adjusting means may be provided at each end thereof forraising and lowering said beam together with the beams 23 which aresupported thereby, such adjusting means being,

arbitrarily shown as nuts 38 threaded upon the ends of verticalsupporting standards 39, the upper ends of the latter being extendedinto vertical openings 40 provided in the beams 20, said beams restingupon said nuts as supports.

From the foregoing, it will be seen that the side of the rake bed may beelevated to a position above the center thereof to feed the straw towardthe center of the bed thoroughly loosening the bundles and that evenwith this adjustment, the movement of the rake bars will not beinterfered with.

What is claimed is 1. A shaking mechanism comprising a bed, a series ofspaced parallel rake bars supported therein for reciprocating movement,means for reciprocating said rake bars, a second series of rake barsdisposed alternately between the bars of said first named series andadapted to be held stationary, and means for simultaneously adj ustablymoving said last named bars to vary the transverse angular plane thereofas a series with relation to said first named bars.

2. A shaking mechanism comprising a bed, a series of spaced parallelrake bars support ed therein for reciprocating movement, means forreciprocating said rake bars, a second series of rake bars disposedalternately between the bars of first named series and adapted to beheld stationary, means for effecting a simultaneous vertical adjustmentof said last named bars, and independent means for simultaneouslyadjustably moving said last named bars to vary the transverse angularplane thereof as a series with relation to said first named bars.

3. A shaking mechanism comprising a bed, a series of spaced parallelrake bars supported.therein, means for reciprocating said rake bars, asecond series of rake bars, disposed alternately between the bars ofsaid first named series and adapted to be held stationary, means forsimultaneously adjustably moving said last named bars to vary theangular plane thereof as a series with relation to said first namedbars, and means for guiding said last named bars individually in avertical plane of movement during the action of said adjusting means.

4. A shaking mechanism comprising a bed, a series of spaced parallelrake bars supported therein for reciprocating movement, means forreciprocating said rake bars, a transverse pivoted beam, a second seriesof rake bars supported-from said beam and disposed alternately betweenthe bars of first named series, and means for moving said beam toselected positions about its pivot.

5. A shaking mechanism comprising a bed, a series of spaced parallelrake bars supported therein for reciprocating movement, means forreciprocating said rake bars, a transverse pivoted beam, standardspivoted at their lower ends to said beam at points between said rakebars, rake bars supported on said standards, a transverse barhavingpivotal connection along its body portion with each of saidstandards, said bar having a projecting end, means for moving said beamto selected positions and -means for guiding the movement of theprojecting end of said transverse bar in a vertical plane during theaction of said adjusting means.

In testimony whereof, We affix our signature, in presence of twowitnesses.
